Question 1: What is a good definition of percent? You should use words symbols, pictures and numerical examples in your definition.
-A percent, to me, is the overall number out of 100. It is expressed as this symbol:%. It supposedly came from the term "cent" which means "100" in French. And since a percentage meant something out of 100, we call it "per" "cent". Some percentages are: 50% (1/2 or half), 25% (1/4 or quarter), and 10% (1/10)...or dime...Haha I'm just kidding.
Here is my percentage web. I included most of what I've already said above, and used gliffy. I'm not a total expert at using it yet so it's not perfect. Hopefully it's understandable.
Question 2:How are three fifths (3/5), 3:2, 60% and 0.6 all the same? Use pictures and words to show your answer.
-These all equal the same thing. The only difference is that they're written in different equivalents. Don't get confused. Let me explain...
-This column shows the different equivalents.
-These are the equivalents for 3/5.
-These are the equivalents for 3:2.
-These are the equivalents for 60%.
-These are the equivalents for 0.60.
No matter how different you write them, they'll always equal the same thing.
Question 3:Show 3 different ways to find 35% of 80.
-Okay, here's my grid that shows 35% percent out of 80.
1. The first way I came up with is to figure out 1%. It's probably the easiest way for finding the answer, and it's always correct. 80/100 (/=divide. I don't think the computer has a dividing sign) =0.8.0.8x35=28. 28=35% of 80.
2. Here's the second way. 80/10=8
8/2=4(5%)
8x3=24+5%(4)=28
3. Here's my third way. 80/10=8
8/2=4(5%)
4x7=28
Question 4:Find a link to blogs that deal with percentages. Leave a comment behind and add the link with a review
-Okay. here are some the one I've found...
-http://linden8am.blogspot.com/ - this class is learning how to convert decimals, fractions, and percentages. I left a comment for one of the students saying that their scribe was very well done and that it was easy to read and was understandable because of the diagrams.
Question 5: The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.
-I think that Ms. Stanzi isn't correct; unless she has more students. See, if Ms. Stanzi claims to have the greater amount of accomplishment, that must mean that she has more students.
Question 6: Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.
a) 16 is 40% of what number?
To find out what the number is, I divided 40% by 40%. 16/40=0.4.
The next thing I did was multiply 1% (0.4) by 100. 0.4x100=40.
40/100=16/40
If you divide 40 by 100, and 16 by 40, you should get the same answer. If you do, then you know that you did this correctly. 40/100=0.4 16/40=0.4
b) What is 120% of 30?
For this question, you could instantly tell that the answer is going to be over 100%.
To find the answer, first you'll have to know that the fraction of this question is 120/100. Knowing that, you'll have to find out the extra 20%.
This is what I did: 30=100%
To find 20%, 30/10=3x2=6
6=20%
The rest is pretty straight forward: 100%+20%=120%.
30+6=36.
36=120%.

Man...I thought I'd never have this done...XD
